Taxonomic concept
Taxon : Vitis aestivalis ,
Accepted Synonym(s) : Vitis aestivalis var. aestivalis,
Vitis aestivalis var. bicolor, Vitis aestivalis var. argentifolia, Vitis
argentifolia
Excluded from concept : Vitis
lincecumii, Vitis aestivalis var. lincecumii, Vitis linsecomii, Vitis
rufotomentosa
NatureServe Concept Reference:
Weakley 2023
Relationship to Flora of North
America: Narrower
Taxonomic Notes: This
treatment is for V. aestivalis is in a narrow sense with varieties
aestivalis and bicolor. Formerly recognized as a variety under V.
aestivalis, Vitis lincecumii is elevated and recognized as distinct
species and Vitis rufotomentosa is recognized as distinct from Vitis
aestivalis (Weakley et al. 2023). While Vitis aestivalis is distinct at
the species level, the distinctiveness of its varieties are still being
investigated (Talavera et al. 2023). Flora of North America (2016) noted
that “the boundaries of the varieties are highly inconsistent and it is
often difficult to apply the varietal concepts in the field.” Vitis
aestivalis var. argentifolia is considered a synonym of var. bicolor
(Moore 1991).

Details on the map elements
Written description of the features on the map.
County Level Features
All county level features report information that as aggregated to the county level. This include text reference to the county (state/county) and spatial point reference that occur within the county.
Counties with a record : This is a binary presence absence map that shows if a specific county has at least one record of the the species from across all evaluated sources.
Sum of records within County : This layer depicts the total number of unique records of a species across all sources within a county.
Counties listed in USDA Plants and/or Bonap Only : These counties only contain a reference from USDA Plants and/or BONAP. There are no identified observation, herberium, or germplasm records from these counties.
Counties with one or more Herbarium or Germplasm record : These counties has at least one herbarium and/or germplasm occurrence. There may be additional record sources within this county.
Counties with observational records only : These counties only have species records from observational datasources such as INaturalist.
Spatial Data Occurrence Features
The spatial data occurrence features are location records with valid latitude and longitude values. As such, all these features are shown on the the map as point locations.
Location based Germplasm Records : Occurrence data with living specimens stored in genebanks or botanical gardens
Location based Herbarium Records with web url : Occurrence data with associated herbarium specimens. That includes a web visable reference for the herbarium records.
Location based Herbarium Records without web url : Occurrence data with associated herbarium specimens. No web visable reference for the herbarium records is included.
Location Based Observation data : Validated records from INaturalist. Only research grade observations are used. These observations are approve as correctly identified by at least two other member of the online community.
General Methods
Gathering Data
Data was gathered at the Genus level from the following
public repositories
Sourced through communication with data owners
- 2023 Botanical Garden Survey – available in the full source data
- BONAP
- IUCN
Data Standardization and Taxonomy
data standardization : All data sets were altered to matched a standard data structure. The specific translation of data sets can be seen here. The compileInputDatasets.r and the specific functions within the functions folder.
Taxonomy: The full synonyms cross walk can be viewed here.
Spatial Reference
When latitude and longitude data is present for a record this information was used to assign the state/country. When valid latitude and longitude values were not provide the state and county reference information was pulled from the attribute data associated with the record. If no valid county information was included in the attribute data, the record was not used within this analysis.
Flora of North America
If state level distribution information was provided for a given specific species, that information was used to filter the states in which counties are evaluated.
